BOTTLE-FILLIN G HEAD;

meogeee.

To all whom it may concern:

Be it known that I, SAMUEL Kara, a citizen of the United States,residing at Columbus, in county of Lowndes and State of Mississippi,have invented certain new and useful Improvements in BottleFillingHeads, of which the following is a specification.

My invention relates to an improvement in bottling machines, and moreparticularly to an improvement in bottle-filling heads for suchmachines; and this present invention is an improvement on the inventiondisclosed in application filed by me January 28, 1908, Serial No.412,994; and also has to do with mechanism which cooperates with the capfinger set forth in a pending application Serial No. 77 8,714, filedJuly 12, 1913.

In the accompanying drawings Figure 1 is a view in side elevation of animproved head,

Fig. 2 is a vertical sectional view, v

Fig. 3 is a view corresponding to Fig. 2 with parts in elevation andportions broken away and showing the bottle projecting into the head andin the position of having the cap secured thereon.

Fig. 4 is a horizontal section on the line 4% of Fig. 2.

Figs. 5, 6, and 7 are horizontal sections on the line 5-5 of Fig. 2,showing the parts in different positions.

Fig. 8 is an enlarged vertical fragmentary seccpion of the lower end ofthe filling-head, an

Fig. 9 is a diagrammatic view illustrating the relation of parts of thebottling machine with respect to the filling head, which cooperatetherewith to cause the automatic and synchronous action of theparts ofmy invention. a

A, represents the filling-head, which is, of course, only one of severalin a completelyorganized machine. This filling-head is supported on ascrew 1 which depends from a rod 2 from a point of support above on acircular track (not shown).

Within the head a receiving chamber '3 is formed. The size of thisreceiving chamber may be varied, and the elevation of the head on thescrew 1 may be regulated to suit the requirements'of bottles of varyingsizes by turning the screw 1 on thethreads of the rod 2 and within thehead A. After this the lock-nut4 is screwed in place, compressing thepacking gasket 5 in the seat ing or conical mouth 9,

by means of a strap 7, so that while the screw 1 is capable of beingturned for raising and lowering the head to regulate the size of chamber3, the filling-head A and rod 2 are held together against axial turning.

l/Vithin the lower end of the head, the throat 8 is stationed. Thisthroat has a flar into which the cap C is forced by the cap-finger 10from below, whereby the cap is held by the frictional engagement of itsflaring edges against the wall of the throat.

In Fig. 2, the cap-finger is in the position of receding from thefilling-head, just after having forced the cap G into the throat 8.

One of the primary objects of my present invention is to prevent theleakage and waste of the liquid to be bottled. This necessitates a tightjoint between the bottleneck and the filling-head especially in thebottling of carbonated water or other effervescent liquids underpressure.

An elastic ring 12 is utilized for this purpose. This ring 12 is held ata point between the throat 8 and the mouth 11 of the filling-head, andthrough the orifice in the center of the elastic ring, the cap-fingerand the bottle-neck pass alternately.

Means is provided for compressing the elastic ring 12 around thebottle-neck, which comprises the compressors 13, 13, of which three areillustrated. These compressors are held slidably in the guide-cup 14secured on the lower end of the filling-head A by screws or other means15, 15. The compressors 13, 13, move radially in this guidecup, theybeing provided on their lower surfaces with radial tongues 16, which fitand slide radially in the slots 17, in the bottom of the guide-cup 14.The outer surfaces 18 of the compressors 13 are correspondingly-curvedeccentric to the center of the guide-cup in the form of cams and outsideof each surface 18 is a groove 19.

A ring 21 is fitted and adapted to turn within the guide-cup 14. Thisring is provided with as many depending lugs as there are compressors,and one lug is fitted to and adapted to traverse each. of the grooves19,

V and to bear upon the corresponding cam surface of a compressor, sothat as the ring 21 is turned in one direction or'theother,

the lugs 20, 20, positively force the compressors 13, 13, radially in orout, and, when inwardly, uniform pressure is applied upon the elastlcring 12 is to resumeits normal proportions on the pressure or thecompressors bemgremoved, yet 1t is well understood thatrubber sooner orlater loses much of its elasticity, especially when strain uponit isal'l in one direction. This is largely, if not wholly, overcome byrepeatedly forcing the cap-finger through the orifice in the center ofthe elastic ring and alternately with each outside compression of thering, thus each time positively restoring the elastic ring to its normalproportions, in this way insuring and preserving the normal,proportionsand dimensions of the elastic ring, thereby notonl-y' greatlyarolongingits life but also getting the benefit of its highestefliciency during'its life.

An outer band lower end of the filling-head is secured to the ring 21 bystuds 23, of which there are three shown in Fig. 5, these studsoperating. through elongated slots 24, 2 in the sides ofthe cup 147. g

The band 22 is provided with two arms 25 i and, 26 which extend out inmore or less opdownwardly alongside the posite directions, one inposition to strike one of the main posts 27 of the ma chine, and theother an obstruction 28 at predetermined intervals, one to turn the band22 in a direction to compress the elastic ring .12 around thebottle-neck when the bottle is being filled, and the other to turn theband to releasethe ring before the head is lifted from the bottle.

t is understood, of course, that the bottlemouth is contracted aroundthe neck of the bottle only when the bottle is being filled, and notwhen the capping or removal of the bottle takes place. 7 y i v v V Theliquid to be bottled is supplied through a fixed pipe 29, j whichextends lower end passing througha slot 3l in the band 22 into the headAat'a point below the bottom of .chamberB. Through this hotlliq'uiddischarges upwardly through the-nozzle 30,,

Aii amount of liqui'l equal to the capacity of the bottle, being filledis discl'iarged through the pipe 29 as determined by the size of thechamber .3. The pressurein the so, I

chamber and bottle become equalized thy v communicating through outlets41 in, the

lower end of the fillin'g h'ea'd A,. and the supply'of liquid tothebottle is thus autoniatically stopped, the liquid passing down throughthe outlets l i nto the bottle, and the air displaced from the bottlerising into the displacement and receiving chamber 3 The displaced, airfrom the bottle prevents the, accumulatioi'i'of liquidiii the chamber 3.

lVhile the c'aibonator pressure isbeing maintained in the bottle, thecap is applied and secured to th bottle by Ftheb ad at the 7 month ofthe bottle being forced beneath the cap G intothe throats, the. taperingmouth 9 of which threat 8 thereb'y'clenches the ,crimped edge of the cap"around the beadedmouth of the bottle. 7

A rubber phig 38'. in thethroatB creates suflicientpressure on "the 'ca0 to insure seating the cap properly, and as a result of its compressionit forces the bottle free from the throat when the headilifts or risesfrom the bottle after the completion or, the capping operation. i 7

Valve 32 remains open until the arm 36 on the band 85 leaves theobstruction, where upon the spring 37 closes the valve 32; This is doneprevious to the filling-head being removed from the bottle, and, bymanage-e the upturned nozzle seer the supply pipe 29, the lossof theliquid remaining in that portion of the pipe below the valye (after thevalve is shut) which, would otherwise flow out is prevented, it beingone of the primay objects o l my present invention, as pre viouslystated, to prevent waste of any of t e liquid to be bottled as; well asleakage 1 a through thejoint formed around th e bottleneck. j Y
